Laser Engraving Machine Focusing Lens

Product Introduction

Laser engraving machine focusing lenses are precision optical components designed to focus laser beams for engraving and cutting applications. Made from high-quality materials like PVD ZnSe, these lenses boast a transmittance rate exceeding 99.9%, ensuring maximum efficiency during operation. With diameters often around 20 mm and focal lengths ranging from 25.4 mm to 190.5 mm, they are engineered to handle various power ranges, typically from 30W to 100W for CO2 lasers.

Product Features

● High-Quality Material: The focusing lens is made of high-quality PVD ZnSe crystal material, which has excellent optical performance and a transmittance of up to 99.9%, ensuring the effective transmission of the laser beam. In addition, the PVD ZnSe material has excellent high temperature resistance and can withstand up to 90W CO2 laser power and adapt to high temperatures and harsh environments, thus ensuring the stability and reliability of the lens in long-term use.

● Lasting Durability: The laser engraving machine focusing lenses are made of high-quality PVD ZnSe material and are treated with double-sided solid coating to ensure excellent long-term durability. The service life of these lenses can be extended by more than 30%, and the replacement frequency is reduced by 50% compared to uncoated lenses.

● Wide Compatibility: These 20 mm laser focal lenses are designed to be compatible with CO2 laser engraving and cutting machines ranging from 30W to 90W. This versatility allows users to integrate them into various systems, including as replacements for K40 laser mirrors. This adaptability ensures that businesses can optimize their existing equipment without the need for extensive modifications.

● Easy Installation: The plano-convex shape of the lenses facilitates straightforward installation, enabling users to mount them in the correct orientation with ease.

Product Maintenance

● Regular Cleaning: Cleaning the lenses is vital to remove dust, fingerprints, and other contaminants that can affect laser performance. It is recommended to clean the lenses every 8 to 10 hours of use, or more frequently in dusty environments. Lenses kept clean maintain up to 99.5% transmittance, compared to a drop to around 90% for lenses with significant contamination. To clean, use an air bulb to blow off loose debris, followed by a lens tissue dampened with acetone, ensuring no streaks are left behind.

● Proper Handling: Handling the lenses with care is essential to avoid scratches and damage. Lenses subjected to improper handling experienced a 25% reduction in optical performance. Always hold lenses by the edges, and avoid touching the optical surfaces. When not in use, store the lenses in protective cases to prevent accidental scratches.

● Environmental Considerations: Maintaining the lenses in a suitable environment can significantly impact their durability. Ideal storage conditions include low humidity and stable temperatures, as fluctuations can lead to condensation on the lens surface. Lenses stored in optimal conditions can last up to 50% longer than those exposed to varying environmental factors.

● Regular Inspection: Conducting regular inspections can help identify any signs of wear or damage early. Inspect the lenses for any visible scratches, chips, or coatings deterioration. Early detection can extend the life of the lenses by up to 30%, as timely maintenance can prevent more severe damage that may require costly replacements.
